Fatal Error: Undefined function

Hi,

I can only suggest that you do a manual re-install of the 4.1 WordPress files. This is done using FTP or the File Manager in your Hosting Panel (Not the WordPress Dashboard).

DO NOT copy over the wp-content folder or wp-config.php file. This holds the sites content and configuration.

I just saw this other thread that is similar to what your experiencing. It give good detail on the process.

Ah, yes, this all sounds helpful… I’ve never done anything like this…

what does this mean? “Get the latest WordPress zip (or tar.gz) file”

Is there a video I can follow? I don’t think I’m wordpress material…

You could maybe hire some help once and awhile.

@gutsybroad – if you want to try this yourself, it’s not actually that hard – just a bit of new info and skills. Lots of people have been in your situation and learned by doing!

You’ll need to have FTP or Cpanel access to your files on the server –

Your hosting company will be able to give you the FTP access info – that’s not part of WP.

Just means download the latest version of WP from here:
